Abstract

The future integration of software-defined network (SDN) with the service-oriented architecture (SOA) paradigm requires new solutions to ensure the quality of service (QoS) according to the users' requirements. The paper presents a user experience-centric approach to traffic engineering and QoS/quality of experience (QoE) support for service-oriented software-defined network (SOSDN) architecture. This approach is to enable end-to-end QoS across the networking and computing domain by monitoring and agreeing on the dynamic state of their functioning. The proposed SOSDN is based on improved traffic engineering techniques, such as adaptive prioritization of services, server selection, and QoS/QoE-based routing. The developed adaptive service prioritization algorithm automatically changes the priority of flows in the network operation mode by the SDN controller for individual users under the concluded service level agreements (SLA) contract. We proposed a mathematical model of correlation of user satisfaction level by QoE score with technical QoS parameters. This model is based on the normalized value of the integral additive QoS criterion. Accordingly, ensuring the ordered user-centric QoS/QoE is carried out by means of proposed multi-criteria adaptive routing of data flows, the metric of which is based on the integral additive QoS criterion. The simulation results showed that, in contrast to known practical solutions, the integrated use of the proposed method of adaptive multi-criteria routing and prioritization of data flows provides a high level of QoE required by users in the SOSDN paradigm.

新兴的面向服务的软件定义网络的流量工程和 QoS/QoE 支持技术

未来，软件定义网络（SDN）与面向服务架构（SOA）范例的整合需要新的解决方案，以根据用户需求确保服务质量（QoS）。本文提出了一种以用户体验为中心的方法，用于面向服务的软件定义网络（SOSDN）架构的流量工程和 QoS/体验质量（QoE）支持。这种方法旨在通过监控和商定网络和计算领域的动态运行状态，实现整个网络和计算领域的端到端 QoS。拟议的 SOSDN 基于改进的流量工程技术，如自适应服务优先级、服务器选择和基于 QoS/QoE 的路由。所开发的自适应服务优先级算法通过 SDN 控制器自动改变网络运行模式中流量的优先级，以满足已签订服务水平协议（SLA）合同的单个用户的需求。我们提出了 QoE 分数与 QoS 技术参数相关的用户满意度数学模型。该模型基于积分加法 QoS 标准的归一化值。因此，确保有序的以用户为中心的 QoS/QoE 是通过建议的数据流多标准自适应路由来实现的，其度量标准是基于积分加法 QoS 标准。仿真结果表明，与已知的实际解决方案相比，综合使用所提出的数据流多标准自适应路由和优先级排序方法，可在 SOSDN 范例中提供用户所需的高水平 QoE。
